A well-tuned mower not only makes your yard look its best, but it also saves you money and keeps you safe. This guide will walk you through the essential steps to tune up your Craftsman mower, making sure it’s ready to tackle the summer season.
A Craftsman lawn mower tune-up encompasses various steps to ensure optimal performance, including cleaning, sharpening, and replacing worn parts. You’ll need to check and adjust the oil, air filter, spark plug, and blade. By diligently completing these tasks, you’ll enhance your mower’s efficiency, extend its lifespan, and achieve a flawless cut on your lawn.
Getting Started: Safety First!
Before diving into the tune-up process, it’s crucial to prioritize safety. Here are some essential steps:
- Disengage the spark plug: Disconnect the spark plug wire to prevent accidental starting.

- Loosen the drain plug and allow the oil to drain completely: Be sure to dispose of the oil responsibly.
- Replace the drain plug: Tighten it securely.
- Fill the crankcase with new oil: Use the recommended oil type and amount specified in your owner’s manual.
Step 4: Replacing the Spark Plug
The spark plug ignites the fuel-air mixture, and a worn-out spark plug can cause misfires, poor engine performance, and increased fuel consumption.
Replacing the Spark Plug:
- Locate the spark plug: It’s typically located on the top of the engine.
- Remove the spark plug wire: Disconnect it from the spark plug.

- Reconnect the spark plug wire: Make sure it’s securely attached.
Step 5: Checking and Adjusting the Drive Belt
The drive belt transmits power from the engine to the wheels, and a worn or loose belt can cause problems with the mower’s speed and maneuverability.
Checking the Drive Belt:
- Inspect the belt: Look for cracks, fraying, or excessive wear.
- Check the belt tension: The belt should have a slight amount of give when pressed.
Adjusting the Drive Belt:
- Loosen the belt tensioner: This is typically located on the frame near the engine.
- Adjust the tension: Move the tensioner to adjust the belt tightness.
- Tighten the tensioner: Make sure the bolt is securely tightened.
Step 6: Testing and Troubleshooting
Once you’ve completed all the tune-up steps, it’s time to test your Craftsman lawn mower.
Testing the Mower:
- Start the engine: Ensure it starts easily and runs smoothly.
- Check the cutting height: Adjust the cutting height to your desired level.
- Run the mower for a few minutes: Listen for any unusual noises or vibrations.
- Inspect the cut: Make sure the blade is cutting evenly and cleanly.
Troubleshooting:
- If the engine doesn’t start: Check the spark plug, fuel lines, and air filter.
- If the engine runs poorly: Check the carburetor, spark plug, and air filter.
- If the mower doesn’t move: Check the drive belt and wheels.
- If the mower doesn’t cut evenly: Check the blade and the cutting height.
